For planting sandmint, well-draining, acidic soil with a pH of 4.5-6.0 is optimal. They thrive in dappled shade but can tolerate full sun in cooler climates. Consistent moisture is vital, yet soggy conditions can lead to root rot. To plant, dig a hole as deep as the root ball and twice as wide. Position the plant so that the top of the root ball is level with the soil surface. Backfill with a mix of soil and organic matter. Water thoroughly and maintain even moisture. Mulching helps retain soil moisture and temperature. Adapting to the specific needs of different sandmint species ensures successful growth.
